As a reminder, Trump is already on National Park passes, and people have been told they will not be admitted if the image is vandalized. At some point, this is not so much branding government services as imposing the images of a personalist regime.

WHAT IS KEN PAXTON AFRAID OF? James Talarico called Ken Paxton to invite him to a Fox News debate. Paxton didn’t pick up. Talarico has accepted four local-TV debates; Paxton has committed to none. Texans deserve more than a Senate candidate who ghosts the debate stage #momsky#sheshed

This is true of universities everywhere. And while universities outside the US don't have issues, I do not think they're on this dreadful scale. This suggests that there is a serious problem with US schools and parents utterly failing to instil ethics and morals before their kids reach university.

Um, not to sound all Widow’s Bay, but this fog/cloud seems quite unnatural In the space of about 10 minutes, the buildings and sun have disappeared
Rising sun with lots of hazy cloud across the sky, buildings are visible The sun just above the buildings with haze covering the sky There is a yellowish glow where the sun is, the rest of the sky is grey cloud, you can still just see the buildings The sun is no longer visible, or the buildings - just thick grey cloud

FT: insurers brace for multimillion-dollar claims caused by rogue AI agents, amid concern that execs like Sam Altman and Dario Amodei could be held liable. They're not "rogue agents". They're defective products created and supervised by negligent humans--and the insurance companies know it.

Just a reminder: Tillis persuaded the woman Hegseth allegedly raped to come forward with her story, and told her that if she did, it would sink the nomination. She did. At great risk to herself. Tillis then cast the deciding vote for Hegseth. Because he’s a goddamned coward.

I don’t think everyone realizes how bad things are for US science: For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget.
